Erectile dysfunction
When a man can't get an erection to have sex or can't keep an erection long enough to finish having sex, it's called erectile dysfunction or impotence. Erectile dysfunction can occur at any age, but it is more common in men older .
Kinds of an impotence:
1 The organic impotence :
2 The psychological impotence
How is it treated?
The penis contains two chambers, called the corpora cavernosa, which run the length of the organ. A spongy tissue fills the chambers. The corpora cavernosa are surrounded by a membrane, called the tunica albuginea. The spongy tissue contains smooth muscles, fibrous tissues, spaces, veins, and arteries. The urethra, which is the channel for urine and ejaculate, runs along the underside of the corpora cavernosa
The first step in the treatment of erectile dysfunction is a physical examination. This is done to rule out disorders such as diabetes, high blood pressure, high cholesterol, kidney disease, alcoholism, or multiple sclerosis, which can cause erectile dysfunction. It is estimated that physical diseases or conditions are the cause of erectile dysfunction .
An important part of the evaluation should be a detailed patient history, which can give the doctor valuable clues about the patient's condition and the degree of severity of the condition. Usually, the doctor will ask about sexual activity and carefully discuss all of the patient's symptoms, which may help determine if the patient is having problems with erection, ejaculation, orgasm, or sexual desire. The treatment of erectile dysfunction is tailored to the individual, with the severity and cause of the erectile dysfunction taken into account.
Vacuum devices are non-drug options for treating erectile dysfunction. The device creates a vacuum around the penis, which draws blood into the penis and allows it to engorge, hence causing an erection. The devices are made up of three parts: a plastic cylinder that is placed over the penis; a pump which draws air out of the cylinder; and an elastic band which is placed around the base of the penis to maintain erection after the cylinder is removed and during intercourse to keep the penis engorged with blood.
Oral medications used to treat erectile dysfunction include selective enzyme inhibitors (e.g., sildenafil Viagra, vardenafil HCl Levitra, tadalafil Cialis) and yohimbine (Yohimbine®, Yocon®).
Selective enzyme inhibitors are available by prescription and may be taken up to once a day to treat ED. They improve partial erections by inhibiting the enzyme that facilitates their reduction and increase levels of cyclic guanosine monophosphate (cGMP, a chemical factor in metabolism), which causes the smooth muscles of the penis to relax, enabling blood to flow into the corpora cavernosa.
Patients taking nitrate drugs (used to treat chest pain) and those taking alpha-blockers (used to treat high blood pressure and benign prostatic hyperplasia) should not take selective enzyme inhibitors.
Men who have had a heart attack or stroke within the past 6 months and those with certain medical conditions (e.g., uncontrolled high blood pressure, severe low blood pressure or liver disease, unstable angina) that make sexual activity inadvisable should not take Cialis®. Dosages of the drug should be limited in patients with kidney or liver disorders.
The most effective means for treatment of an impotence is viagra. It also the most popular means. Many men are afraid to go to the doctor behind the prescription on viagra. The reason for it not desire to disclose about the illness. Therefore there is an opportunity to receive the prescription for viagra on the Internet. It simply, conveniently and anonymously.
